i08 GroundwaterElevationSeasonal Contours

This service depicts contours of estimated groundwater piezometric surfaces in the unconfined or uppermost semi-confined aquifers. Contours represent and elevation above mean sea level (in feet, NAVD88), by year and season (fall or spring). The contour interval is 10 ft.

For 'Elevation' type contours, contours represent lines of equal elevation of the estimated groundwater level surface above mean sea level. Higher contour values indicate higher elevations of the estimated groundwater level. Negative values indicate groundwater surface elevations below mean sea level.
